Hi folks,
First time post. I purchased a 2019 2500 4x4 with 6.4L engine back in May 2021. It had under 43000 miles and since then, I've put about 8,000 miles on it. I've pulled a 30' travel trailer around Texas without issue. In fact, the truck drives well with or without the trailer and I have been using the tow/haul button without any issue.
We left for Colorado last week (from east Texas) with the RV and had no issues until just 5 miles outside of Golden where we were going to camp. The check engine light came on. I had been monitoring the gauges and there had been no significant change in temps/pressures. My first thought was altitude issues but that the computer should've been adjusting for that.
After dropping off the RV, I drove to OReilly's to get the code read but it seemed that the tranny was shifting a little sluggish. The code was P219B (bank 2 air-to-fuel ratio). I took it to the Dodge house the next morning but they were swamped and couldn't do much other than verify the code. So far each Dodge house I call seems to be booked out for 1-2 weeks.
That's the backstory. I've had the CEL come on 3 times. When this happens, the tranny seems to hold the gear too long either going up or down. In fact, one time I tried to pass a vehicle downhill and the truck would not shift from 3rd gear. I could not pass without getting into some high RPMs. Basically there is something wrong/different after the CEL. Each time I have cleared it and shut the truck down for 10-30 minutes. Sometimes it will drive better; sometimes not.
After it cools down or overnight, it drives better.
When I am NOT towing, the truck drives like a dream (other than the trip to OReilly's). No issues. Great gas mileage. Smooth shifting.
I have now started to tow without the Tow/Haul button. So far, no issues. I cannot guarantee that the CEL is related to the Tow/Haul, but it sure seems like it. I've never had a truck with "limp home mode" before so I can't really say if that is the reason for the sluggish feeling in the tranny.
Asking for advice since I have been unable to find a dealership or independent mechanic who isn't overbooked. We still have more of this trip to go before we head home. I'd like to get this fixed or some advice on what to do.
Thanks in advance.
Bruce
